Dodge Rear Spoilers;

Dodge is a United States-based brand of automobiles, minivans, sport utility vehicles, and trucks, manufactured and marketed by Chrysler LLC in more than 60 different countries and territories worldwide. Founded as the Dodge Brothers Company in 1900 to supply parts and assemblies for Detroit's growing auto industry, They began making its own complete vehicles in 1914. The brand was sold to Chrysler Corporation in 1928, passed through the short-lived DaimlerChrysler merger of 1998-2007 as part of the Chrysler Group, and is now a part of Chrysler LLC owned by Cerberus Capital Management, a private equity investment firm.

Spoilers  generally function by disrupting or diffusing the airflow passing over and around a moving vehicle as it passes around the spoiler. This is accomplished by increasing the amount of turbulence flowing over the shape, "spoiling" the laminar flow and providing a cushion for the laminar boundary layer. Applications are varied, including using body panels, or most typically by adding an extruding attachment. Occasionally spoilers are added solely for appearance with no thought towards practical purpose.

The spoilers  is an automotive aerodynamic device whose intended design function is to 'spoil' unfavorable air movement across a body of a vehicle in motion. Spoilers are often fitted to race and high-performance sports cars, although they have become common on passenger vehicles, as well. Some spoilers are added to cars primarily for styling purposes and have either little aerodynamic benefit or even make the aerodynamics worse.

Spoilers for automobiles are often incorrectly confused with, or even used interchangeably with, wings. Automotive wings are devices whose intended design is to generate down-force as air passes around them, not simply disrupt existing airflow patterns.

The main design goal of spoilers in passenger vehicles is to reduce drag and increase fuel efficiency. While many often imitate wings and airfoils, these serve mostly decorative purposes. Passenger vehicles can be equipped with front and rear spoilers. Front spoilers, found beneath the bumper, are mainly used to direct air flow away from the tires to the underbody where the drag coefficient is less. Rear spoilers, which modify the transition in shape between the roof and the rear and the trunk and the rear, act to minimize the turbulence at the rear of the vehicle.

Sports cars are most commonly seen with front spoilers and rear spoilers. Even though these vehicles typically have a more rigid chassis and a stiffer suspension to aid in high speed maneuverability, a spoiler can still be beneficial. This is because many vehicles have a fairly steep downward angle going from the rear edge of the roof down to the trunk or tail of the car. At high speeds, air flowing across the roof tumbles over this edge, causing air flow separation. The flow of air becomes turbulent and a low-pressure zone is created, increasing drag and instability. Adding a rear spoiler makes the air "see" a longer, gentler slope from the roof to the spoilers, which helps to delay flow separation. This decreases drag, increases fuel economy, and helps keep the rear window clean.
